The application of laser powder bed fusion (LPBF) on TC4 titanium alloy is an important way to achieve lightweight and integration in aviation, aerospace, medical, electronics,and other fields at present. In this paper, the effects of laser powder bed fusion on microstructure and defects of TC4 titanium alloy and its mechanism are systematically summarized. The research status of the influence of LPBF parameters and heat treatment methods on the tensile properties of TC4 alloy formed by LPBF is reviewed in detail as well. On this basis, in view of the bottleneck on application of LPBF TC4 titanium alloy at the present stage, the research status of fatigue properties and fracture toughness of TC4 alloy formed by LPBF is systematically summarized, and the effective post processing methods to improve the fatigue property and fracture toughness of TC4 titanium alloy fabricated by additive manufacturing are pointed out, and the development trends are also discussed.
